Single image camera with i> erbst3pannversahluß

The invention relates to a single-image film camera with a self-tensioning mechanism .

In such a camera, in which the shutter every time stretched by the pile winding or film transport process when the film is advanced one frame length, the self-tensioning when using a film

can easily be achieved with edge perforations, as a ratchet wheel for transporting the film with edge perforations a locking device can be coupled. if however, a film without perforations, e.g. a roll film with a cover paper, is used, an against the back surface of the cover paper pressed friction wheel rotated by frictional engagement by a predetermined angle each time the film t wound up without perforations or advanced by an image length the degree of rotation is determined by a suitable device and when it is reached of the setpoint the film transport is ended. Here, the rotation of the friction wheel through the frictional engagement with the The effect of the film is that it is hardly possible to obtain the force required to drive the shutter clamping device from the friction wheel to decrease.

La also the angle of rotation of the transport button or lever operated from the outside of the camera for the film without Perforations as a result of the increasing thickness of the Coil wound film layer decreases, this member can not simply be used to close the shutter tighten. The stroke of the locking device must always be the same.

Thus, the integral with the roller 17 gear wheel 1b is rotated, so that diy V / elle 19a (Fig.H) and that of the ^; . ¥ elle 1Ma-, carried disks 20 and 21 also rotated in the direction of the arrow (Pig. 3) via a suitable gear mechanism. The projection 26a on the lever 26 is pressed against the outer periphery of the disc 21, which is loosely placed on the shaft 19a , and exerts a braking force on the disc 21, so that the disc 20 first of the disc 21 by one by The position of the elongated hole 22 leads to a certain degree of advance, as a result of which the loop-shaped spring 24, which tries to expand outwards, is tensioned. Lord, the pin 23 on the disk 21 has reached the end of the elongated hole 22 , the notches 20a and 21a on the two disks 20 and 21 are in overlap. Since the pin 23 is held in place by the rear end (the upper end in FIG. 3) of the elongated hole , the disks 20 and 21 are then rotated together in the direction of the arrow (FIG. 3). The diameter of the roller 17 is selected so that when the shaft 19a makes substantially one revolution, the film is transported by one frame length. So when the projection 26a on the lever 26 engages in the overlapping rotating notches 20a and 21a, as mentioned above, the pawl at the other end of the lever 26 engages in the

The self-tensioning device according to the invention is particularly suitable for use in a small camera thanks to its simple construction in which a mechanism is used which takes advantage of the tension and relaxation of the above-mentioned spring band so that the rotation even after the film has been transported or wound up the shaft, with the help of which the film reel is driven from the outside of the camera, can further be used for tensioning the shutter release mechanism when the film transport is stopped.

i / hen is coiled at the above-described construction of the film 16 and the rotation of the lock wheel is prevented by the lever 26, as previously described, the ratchet wheel 7 can not continue to rotate even if the knob 2 is in fc the arrow direction is further rotated . As a result, the ball 111 is prevented by the pin 112 from penetrating into the narrower space, so that rotation is no longer transmitted to the shaft 6. The spool shaft therefore stops so that no film is wound onto the spool. If the button 2 (FIG. 1) is now rotated further in the direction of the arrow, the locking device is tensioned via the gear 13 carried by the shaft 8b and the gear H which is in engagement with it.

An arm of the pivot lever 211 is fork-shaped and one leg of the fork has an arc-shaped edge, which acts on the lining 8b attached along the circumferential collar 8a of the disc 8.

A pin 7a protruding from the ratchet wheel 7 is arranged between the fork legs. The other arms of the pivot lever extend essentially parallel to one another and are connected to one another by means of a tension spring 212 « The circular arc-shaped edge of a fork leg is therefore striving to be against the length of the circumferential collar of the Disc 8 attached lining due to the force of the spring 212 to be pressed. Furthermore, since one end P of the circular arc-shaped Edge portion, the pivot 210 of the pivot lever 211 and the center of the disc 209 are in a line, the above mentioned circular arc-shaped edge of the fork leg inevitably pressed against the covering 8b when the link 211 is around | The pivot pin is turned clockwise (Fig. 8). Will on the other hand, if the link 211 is rotated counterclockwise about its pivot, the arcuate edge of the fork leg becomes moved away from the lining 8b, so that the braking force is eliminated or drops (Fig.1) is rotated in the filing direction, the disc 8, which is integral with the shaft 8b, which in turn is coupled to the button 2, in the direction of the arrow

rotated, causing the disc 209 to mediate the member 211 pressed against the lining 8b rotates in the same direction as shown by the arrow in FIG. The shaft 6 carrying the disc 209 therefore rotates the spool 15, which rotates in synchronism with the part 6a with enlarged diameter rotates in the direction of the arrow, whereby the film 16 is wound on the spool.

As soon as the pawl of the lever engages the teeth of the ratchet wheel, the rotation of the ratchet wheel 7 is stopped, even if the knob 2 is turned further in the direction of the arrow '. The pressing of the driver members 211 against the Circumferential collar of the disk 8 is prevented by means of the pins 7a protruding from the ratchet wheel 7, and consequently no rotation is transmitted to the shaft 6. The spool therefore stops, so that the film no longer on the Coil is wound.

A fourth embodiment will be described below with reference to FIGS of the invention described. The gear 13 and the ratchet 311 are carried by the shaft 6 side by side. A pivotable pawl 313 is rotatably mounted on a pivot 312 in a suitable peripheral part a disk 310 arranged within a recess in the ratchet wheel 7 is fixedly attached. These

When it is wound up, the film contacts the roller 17, which has a high coefficient of friction, so that it is rotated. In this case, the toothed wheel carried by the surface of the guide roller 17 drives the toothed wheel 19 by means of a suitable intermediate gear in the direction of the arrow (FIG. 10).

V / ie also in the previous embodiments, the rotation of the ratchet wheel 7 t ^es P ^err ^> as soon as the pawl of the lever engages the ratchet wheel 7, so that the rotation of the knob 2, ie the rotation of the ratchet wheel 311 causes the Pawl 313 rotates counterclockwise about pivot 315 as an instantaneous center, disengaging pawl 313 from ratchet 311, slides over one tooth of ratchet 311, and engages the next tooth space. This movement is repeated when the shaft 6, ie the ratchet wheel 311, is rotated in the same direction. During this movement , the disk 310 can only perform reciprocating movements about its axis within a very small range of angles, but it can never rotate. Furthermore, as soon as the rotation of the ratchet wheel 7 is stopped, the ratchet wheel 311 allows the ratchet pawl 313 to move back and forth only within a very small angular range when it snaps into place, free continuous rotation of the ratchet wheel 311 being possible.

The invention thus provides a self-tensioning device for a camera in which a locking clamp is fixedly secured on a shaft which is coupled to a winding knob, with which the winding
